Pressure bonding device

A pressure bonding device comprising a base, a sealing cover, and a pressurizing assembly, wherein the base is configured to place a to-be-pressed member;

• the sealing cover is configured to cooperate with the base to form a sealing space between the base and the sealing cover during pressure bonding operation;
• the pressurizing assembly is connected to the sealing cover, and the pressurizing assembly is configured to apply pressure to a flexible medium in the sealing space to cause the to-be-pressed member to be pressed under the pressure of the flexible medium;
• wherein the pressurizing assembly comprises a piston, the piston is located within the sealing cover and is slidably sealed with an inner wall of the sealing cover, and the sealing space is formed between the sealing cover, the piston and the base;
• the piston can apply pressure to the flexible medium in the sealing space when moving towards the base;
• wherein the pressurizing assembly further comprises a piston rod and a driving device, the driving device is located outside the sealing cover, one end of the piston rod is connected to the driving device, and the other end of the piston rod passes through the sealing cover and is connected to the piston;
• the driving device is configured to drive the piston to move towards or away from the base within the sealing cover;
• wherein the pressure bonding device further comprises a support frame, the support frame comprises a support plate, a guide plate, and several first guide shafts, the driving device is fixed on the support plate;
• the guide plate is located between the support plate and the sealing cover, one end of each first guide shaft is fixedly connected to the support plate, the guide plate is slidably connected to each first guide shaft;
• the driving device is connected to the guide plate, and one end of the piston rod is connected to the guide plate;
• the driving device is configured to drive the guide plate to move along an axial direction of the first guide shaft.
